AnnaLynne McCord, best known for her role on the CW’s “90210,” broke down in tears on stage in front of hundreds during the Somaly Mam Foundation’s Life is Love Gala while recalling being raped as a child and becoming suicidal.

McCord took the stage at Wednesday’s event at Gotham Hall to help raise money for the organization, which was founded by Cambodian ­human-rights activist Somaly Mam and works to end human trafficking and sex slavery. ­McCord told the crowd, which included Katie Couric, Ron Livingston and Dylan McDermott, “We did not raise enough money tonight.” Then she launched into her traumatic personal story.

“I was raped. I was abused as a child. This is so important to me,” she said. “I was suicidal. I cut my arms up. I wanted to die. I had a bottle of pills in a hotel, and I was ready to end it all, and something, I don’t know what, led me to Somaly Mam. So I can stand here tonight and ask you, ‘Is there five dollars that you don’t need? . . . Five dollars you can give to this woman who saved my life?’ ”

McCord burst into tears, with Mam taking the stage to hug her and hold onto her as the actress begged the crowd to raise their hands to pledge money, rather than inputting numbers into an iPad carried around by a staffer. “I don’t want to see iPad bull[bleep],” she said and began calling out numbers.

“I know this is unorthodox. I know this is crazy, but no normal people change the world, so be a bit audacious and spend a little bit more and write it off later . . . Even if you’re liberal, you know you get those tax breaks, come on,” ­McCord said. Her pitch scored an additional $35,000 for the organization. The event raised more than $700,000.

McCord revealed details of her ordeal during another Somaly Mam event last year, saying: “I had a very similar experience to what these girls go through 20 times a night. It happened to me once by somebody that I knew, and it is a very ­interesting thing to feel that you do not have the voice to say ‘no’ . . . I did not know how to say, ‘I don’t want this. Please do not do this to me.’ ”
